Basically different clock speeds. Clock speed is, effectively, how man ‘transitions’ something can make per second. 800 has a faster clock speed than 667, which equates to more transfers-per-second and thus more MB/s in transfer speed.
What is the highest DDR2 RAM?
The maximum capacity on commercially available DDR2 DIMMs is 8GB, but chipset support and availability for those DIMMs is sparse and more common 2GB per DIMM are used.

Can I use 667MHz ram in 800MHz supported motherboard?
Yes, in general, you can use memory of any speed as long as it fits. This is because memory modules will tell the computer how to use it through something called an SPD table .
Does 4GB DDR2 exist?

Is DDR2 good for gaming?Is DDR2 RAM good for gaming? – Quora. no it is absolutely not. if you dont want to invest a lot of money get ddr3, for GAMING (thats what you are asking for) take ddr4.
Article first time published onWhat are the 3 types of RAM?
- Static RAM (SRAM)
- Dynamic RAM (DRAM)
- Synchronous Dynamic RAM (SDRAM)
- Single Data Rate Synchronous Dynamic RAM (SDR SDRAM)
- Double Data Rate Synchronous Dynamic RAM (DDR SDRAM, DDR2, DDR3, DDR4)
Why is DDR2 so expensive?
Why is DDR2 more expensive than DDR3 & 4? – Quora. Supply and demand. No one is making DDR2 anymore, and some people are still using computers that use DDR2. So since no one is manufacturing it, as supply dwindles, the price doesn’t come down like you’d expect on older tech since it’s still in demand.
Is DDR2 obsolete?
it’s not made anymore. if you are incredibly lucky you can find some old stock someone still has. or more than likely you’ll have to get it from a used source.
How much faster is DDR4 than DDR2?
DDR2 memory is at the same internal clock speed (133~200MHz) as DDR, but the transfer rate of DDR2 can reach 533~800 MT/s with the improved I/O bus signal. … DDR4 SDRAM provides the lower operating voltage (1.2V) and higher transfer rate. The transfer rate of DDR4 is 2133~3200 MT/s.
What does CAS latency mean for RAM?
The CAS latency is the delay between the time at which the column address and the column address strobe signal are presented to the memory module and the time at which the corresponding data is made available by the memory module.
Can I put DDR RAM in a DDR2 slot?
DDR(1) and DDR2 are not compatible, so choose either one. There are motherboards (check Asrock) that can handle both memory types, but in different slots, and only one type at a time.
What does the L stand for in DDR3L?
L stands for “low voltage,” which is 1.35V instead of 1.5V. If your computer supports or requires 1.35V RAM, it will use less power, reduce heat and extend battery life, DDR3L is the designation some manufacturers use to say the RAM runs at 1.35V.
What is PC4 RAM?
PC4 means the number of bits transferred per second. 2133 X 8 = 17060. So you motherboard spec says it support 2133 MHz speed.

Is 4G RAM good for laptop?
If it’s simple stuff like browsing the web, streaming videos, and watching YouTube, 4GB is probably plenty. If you’re doing more memory intensive things like using photoshop, having video chats on Zoom, you probably want to jump to 8GB at at least. If you’re editing video, you probably want to jump to 16GB.
What is difference between DDR2 and DDR3 RAM?
DDR2 RAM provides four knowledge transfers per cycle, whereas DDR3 will increase the amount to eight. forward a base clock speed of 100Mhz, DDR RAM can offer sixteen hundred MB/s of information measure, DDR2 provides thirty two hundred MB/s, and DDR3 provides 6400 MB/s. a lot of is usually better.
What is the maximum size of DDR3 RAM?
The DDR3 standard permits DRAM chip capacities of up to 8 gigabits (Gbit), and up to four ranks of 64 bits each for a total maximum of 16 gigabytes (GB) per DDR3 DIMM.
Can I use PC3 RAM in a PC2 motherboard?
No. PC3 is DDR3 ram. PC2 is DDR2 RAM. They are notched differently and if you try to jam one or the other into another slot you could risk damaging your board.
Is DDR4 better than DDR2?
DDR2 memory is at the same internal clock speed (133~200MHz) as DDR, but the transfer rate of DDR2 can reach 533~800 MT/s with the improved I/O bus signal. … DDR4 SDRAM provides the lower operating voltage (1.2V) and higher transfer rate. The transfer rate of DDR4 is 2133~3200 MT/s.
Is DDR3 still good?
There’s very little difference when it comes to performance, yes DDR3 RAM is still good. Really, only noticeable difference/reason to use DDR4 is because certain newer motherboards/chip architectures require it.
Is DDR3 RAM good for gaming?
Higher end systems that use DDR3 memory can still be respectable gaming rigs in 2020. It won’t quite keep up with a modern CPU, but a Core i7–4770K or 4790K is still a decent gaming processor.

Can DDR3 be used instead of DDR2?
DDR3 is not backwards compatible with DDR2. While both types of modules have similar numbers of pins, the notches in the PCB are in different locations. In other words, a DDR3 module cannot be placed in a DDR2 memory socket, and vice-versa.
Why is Sodimm so expensive?
The SODIMMs are rare and expensive. Once modules go out of mass production, the prices are liable to be unstable. If you are saying why is RAM so expensive relative to what your budget is, then your budget is the one variable you can address in that equation.
